We consider Pogorelov estimates and Liouville-type theorems to parabolic k-Hessian equations of the form utσk(D2u) = 1 in n × (, 0]. We derive that any k + 1-convex-monotone solution to utσk(D2u) = 1 when u(x, 0) satisfies a quadratic growth and 0 < m1 ut m2 must be a linear function of t plus a quadratic polynomial of x.

抛物线 k-Hessian 方程的 Pogorelov 估计和刘维尔型定理

我们将 Pogorelov 估计和刘维尔型定理考虑为抛物线ķ-Hessian 方程的形式 - σķ(D2) = 1n × (-, 0]. 我们得出任何ķ + 1-凸单调解决方案 - σķ(D2) = 1什么时候(X, 0)满足二次增长和0 < 1 - 2必须是一个线性函数加上一个二次多项式 X.
